The study of Mahmood Afghan attack to Kohkiloyeh & Behbahan to Badaye Akhbar manuscript

The topic of Mahmood Afghan attack to Isfahan and decline of 200 years safavid government is of topics that has been considered by many internal & external researchers who look at it in different views. Although we know that Afghans hit the last stroke to the Safavid government which about one century before that time had been fallen into the weakness & decline and also governed Iran about 7 years (1135 _ 1142); In spite of their efforts toward maintaining power and developing government C They couldnt put in practice their dominance on noticeable regions of Iran C resistance of cities Yazd E Khansar and their useless efforts. Among these cities E Behbahan and Kohkiloyeh didnt accept Afghan governance and resist against them E but we have only few reference about that (few lines are wrriten about that). Badaye Akhbar is an unique manuscript which was written by skilled writer known as Mirza Abdollah Nabi E a Behbahan writer who wrote in detail the story of Behbahan people resistance and defence against Mahmood Afghan attack. No doubt E if there wasnt an obligated historian like him, we havent known about this attack and defence or in other words we havent known about part of the history of that district. Severe defence of Behbahan people against Afghans which last about 36 days in 1136 led to failure of attackers reperformance one year later(1137).
